Polymer

Every protein is a polymer composed of units called amino acids.

Scientists at the University of Warwick in England, led by chemist David Haddleton, developed the five-centimeter square bandage that contains a special polymer adhesive infused with the painkiller.

The elasticity of this polymer isn't the best suited to our ends.

The water absorbency of the anionically starch-grafted AA/AM absorbent is markedly affected by the pH of the buffer solution at different ionic strengths. The charge of the ionic monomer affects the pH sensitivity of the superabsorbent polymers. An acidic superabsorbent normally ionizes at high pH but unionizes at low pH.

Similar studies of rats have employed four different intracranial resorbable, slow sustained release systems—surgical foam, a thermal gel depot, a microcapsule or biodegradable polymer beads.
